ER 4/19

Hard epsoide to watch, it being about father's and not having a good relationship wiht mine, blah blah blah. That poor dad, having to be told everyday that his son is dead. Who is the guy that is playing Tony's dad? I know that guy but for the life of me I can't think of his name. I really hope that Tony is her dad. Nela needs to pick a guy, just one guy. I know that she likes Tony and everything but that is just to much work. Why isn't he her dad?
